A creepy brain doctor accused of raping and molesting multiple women in New York, New Jersey and Pennsylvania has been busted by the NYPD.

Dr. Ricardo Cruciani, 63, a wealthy neurologist who worked at Beth Israel hospital, was arrested Tuesday for allegedly raping and sexually assaulting six female patients in New York, mostly in 2013, police and prosecutors said.

He is accused of forcing oral sex on the women, as well as raping them or attempting to rape them when they were incapable of consent, court records show.

At his arraignment, Cruciani, who lives in Wynnewood, Pa., posted a $1 million bond and then hid from reporters in the lobby of the Manhattan district attorney’s office.

Prosecutors recommended at least a decade behind bars and want him to plead guilty to assaulting all six women. He pleaded not guilty.

The investigation began when a victim called a sex abuse hotline and reported the assaults, sources said.

Cruciani left behind a trail of other victims in other states, according to authorities.

In September, Philadelphia police busted Cruciani on sexual assault and harassment charges based on accusations from seven women.

At the time, he was the chairman of the neurology department at Drexel University Hospital. The university fired him but he managed to avoid jail time. A Pennsylvania judge sentenced him to probation in November and ordered his medical license revoked.

Altogether, at least 17 women in Pennsylvania, New York and New Jersey have accused him of sexual misconduct going back more than 12 years, according to the Associated Press. The NYPD had previously investigated Cruciani after a 17-year-old girl stepped forward, the AP reported. Detectives closed that case without charging him.
